Give the timestamp info after the first RTP packet to RTCP
...
Previously the information was given too early which meant that
RTCP used incorrect information when calculating the RTP timestamps
for RTCP Sender Reports

Send RTCP status reports every 5 seconds
...
5 seconds is the mimimum interval betwen RTCP packets required by
the spec. Some time in the future a better scheduling algorithm
will be implemented for RTCP reports

Calculate RTP timestamp properly
...
Generating NTP and random RTP timestamp allows us to sync different
media streams and provide useful RTP timestamps for RTCP Sender Reports
2019-06-26 12:32:08 +03:00
00bca33585
Add clock_rate_ variable for RTP timestamp calculations
...
Clock rate varies based on the the media sent and it's used to
calculate the RTP timestamp from t = 0 time

2019-06-25 11:10:00 +03:00
3868fe83d9
Remove the constraint where Sender Report must contain Receiver Report Blocks
...
The session may consist of single writer and multiple readers. In this
case it must still be possible to send RTCP status reports to readers.

Rename functions more logically
...
Use only the word "participant" and not both "peer" and "participant"
2019-06-25 09:46:00 +03:00
0c7b3da4e4
Remove set_sender_ssrc()

It is no longer used because the status of the sender is checked
on every RTP packet

Update the sequence properly after each packet
2019-06-25 09:37:10 +03:00

2019-06-24 11:40:59 +03:00
97d7691ba2
Remove the check for first message in reader.cc
...
RTCP keeps a list of participating members and will do necessary
initializations if this is a first message from a peer
2019-06-24 11:37:44 +03:00
2fe24c26b4

2058cec187
Check has the RTCP instance received any messages from remote
...
If we haven't received any message, it's impossible to include the
correct SSRC to RTCP packets. Thus we should return early if the
session doesn't have any participants
2019-06-20 13:12:25 +03:00

The previous name was misleading because not all participant are
senders

Add multicast files
2019-06-20 09:22:10 +03:00
44e6655c68
Remove some of the RTP session statistics functions
...
They gathered unused information (ie. not required by the spec)
so they can be removed
2019-06-20 08:36:44 +03:00
9088f9c6d2
Overload recvfrom() to accept sender and bytes_read parameters
...
If the caller doesn't need them, he can just call one of the overloaded
functions

6075c7bdbc
Add overloaded sendto() which doesn't take the bytes_sent parameter
2019-06-19 09:16:57 +03:00
ea1db5338f
Add RTCP packet handling functions for all packet types
...
Most of the functions don't do much just yet because we don't have
an API for the user for querying RTCP reports etc.
2019-06-19 08:09:28 +03:00
94117e95d8
Add APP/BYE/SDES sending routines

Don't deallocate the frame parameter
...
We don't know if it's allocated on the heap or the stack
so deallocating it is dangerous
2019-06-18 10:32:34 +03:00
a0a60d1972
Rename report_cnt to count in RTCP header
...
Different packets have different counts (not all packets contain reports),
so the name was misleading
2019-06-18 10:29:31 +03:00
